交叉编译 armhf 并安装静态库

Question

我已经设置了一个交叉编译的 docker 实例。简而言之，我开始设置

apt-get update
apt-get install binutils-multiarch

dpkg --add-architecture armhf
# Manually add correct armhf repositories to /etc/apt/sources.list
apt-get update
apt-get install libudev-dev:armhf

在这最后一步中，我收到以下错误：

The following packages have unmet dependencies:
libudev-dev:armhf : Depends: libacl1:armhf (>= 2.2.51-8) but it is not going to be installed
                    Depends: libblkid1:armhf (>= 2.19.1) but it is not going to be installed
                    Depends: libc6:armhf (>= 2.17) but it is not going to be installed
                    Depends: libgcc1:armhf (>= 1:3.5) but it is not going to be installed
                    Depends: libkmod2:armhf (>= 5~) but it is not going to be installed
                    Depends: libselinux1:armhf (>= 2.0.65) but it is not going to be installed
                    Depends: libudev1:armhf (= 229-4ubuntu4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

手动安装这些不是一个选项，因为libc6:armhf与当前安装的 amd64 libc6 冲突，最终会覆盖这个包。我只想设置libudev:armhf包，以便我可以链接到它。

/etc/apt/sources.list：

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main restricted
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial-updates main restricted

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial universe
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial-updates universe

deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security main restricted
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security universe
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security multiverse

运行apt-cache policy libudev-dev:{amd64,armhf}输出如下：

libudev-dev:
  Installed: (none)
  Candidate: 229-4ubuntu21.4
  Version table:
     229-4ubuntu21.4 500

Answer 1

第 1 步 - 打开终端：

按Ctrl+ Alt+ T。

第 2 步 - 备份：

执行：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

第 3 步 - 打开编辑器：

执行：

sudo gedit /etc/apt/sources.list

如果需要，您可以使用其他编辑器。

第 4 步 - 编辑sources.list：

删除这里的所有内容并添加这些：

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main multiverse restricted universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial main multiverse restricted universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial-updates main multiverse restricted universe
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security main multiverse restricted universe

保存并退出。

第 5 步 - 更新您的存储库索引：

执行：

sudo apt update

第 6 步 -libudev-dev为armhf架构安装：

执行：

sudo apt install libudev-dev:armhf

说明： Multiarch 包需要在所有架构上安装相同的版本。所以，你应该有libudev-dev:armhfversion 229-4ubuntu21.4，但你当前的存储库配置不包括这个版本。因此，您应该添加xenial-updates支持此版本的行。

关于其他建议添加频道，我建议您添加这些以防出现问题。
